Description

Prezračevalna naprava Opis izuma Področje tehnikeVentilation device Description of the invention Field of the technique

Prezračevanje; rekuperacija toplote; prenosnik toplote; protitočni prenosnik toplote Prikaz problema V starejših zgradbah se ne pojavljajo problemi glede pomanjkanja svežega zraka, saj so zaradi načina gradnje in uporabljenega materiala zgradbe same po sebi dihale. Prav tako je bila cena energije nižja in s tem so bili tudi stroški ogrevanja nižji. Zaradi predpisov so nove stavbe bolj tesne in večja tesnost stavb je v številnih primerih povzročila tudi negativne učinke, kot je zadrževanje nekakovostnega zraka in vlage v prostoru (rosenje stekel in nastajanje zidne plesni).Ventilation; heat recovery; heat exchanger; countercurrent heat exchanger Problem overview Older buildings do not have problems with the lack of fresh air, because they are breathing in their own way due to the construction method and the material used. Also, the price of energy was lower, and thus the heating costs were lower. Due to regulations, new buildings are more tight and more tightness of buildings has in many cases also caused negative effects, such as the retention of poor quality air and humidity in the room (dewing and wall molding).

Novogradnje so zaradi vedno večjih potreb po energijski varčnosti postale veliko bolj tesne. Ker ni več naravnega prezračevanja prostorov, je nujno potrebno prisilno prezračevanje. Ena izmed možnih rešitev je tudi lokalni prezračevalni sistem s prenosom toplote od notranjega zraka na sveži, zunanji zrak (rekuperacija toplote).Due to the increasing demand for energy savings, new buildings have become much more tight. As there is no longer natural ventilation of the rooms, forced ventilation is indispensable. One of the possible solutions is also a local ventilation system with heat transfer from the indoor air to fresh, outdoor air (heat recovery).

Dosedanji lokalni prezračevalni sistemi s prenosom toplote pa ne poznajo postavitve sestavnih delov tako, da bi bilo omogčeno izdelati napravo v obliki ozke dolge prizme. Na zunanjih stenah je vedno več oken in ta postajajo vedno večja, tako da je vedno manj možnosti za postavitev ploščatih lokalnih prezračevalnih sistemov.The existing local ventilation systems with heat transfer do not know the layout of the components in such a way as to make it possible to construct a device in the form of a narrow long prism. There are more and more windows on the outer walls, and they are getting bigger, so there is always less room for placement of flat local ventilation systems.

Priporočljivi bivalni pogoji v prostoru so pri temperaturi med 18 in 22eC in relativni vlagi med 35 in 70%. Previsoka relativna vlage je neprijetna in lahko povzroči kondenzacijo vodne pare na hladnih površinah zidov in stekla ter rast glivic na hladnih delih sten (predvsem v vogalih zunanjih sten). V ustrezno zastekljenem in izoliranem objektu potrebujemo v povprečju 50% energije za ogrevanje in hlajenje stavbe na temperaturo primerno za udobno in kakovostno bivanje, drugih 50% energije pa potrebujemo za prezračevanje bivalnih prostorov. Zato je potrebno poleg ustrezne zasteklitve in izolacije objekta poskrbeti tudi za ustrezno prezračevanje prostorov. Z uporabo lokalnih prezračevalnih sistemov z rekuperacijo toplote pa dodatno zmanjšamo rabo energije in stroškov.The recommended living conditions in the room are at a temperature between 18 and 22eC and relative humidity between 35 and 70%. Excessive relative humidity is unpleasant and can cause condensation of water vapor on cold surfaces of walls and glass, and the growth of fungi on cold parts of the walls (especially in the corners of the outer walls). In a properly glazed and insulated building, we need an average of 50% of energy for heating and cooling the building to a temperature suitable for comfortable and quality living, while the other 50% of energy is needed for ventilation of living spaces. Therefore, in addition to the appropriate glazing and insulation of the building, it is necessary to provide adequate ventilation of the premises. By using local ventilation systems with heat recovery, we further reduce the use of energy and costs.

Stanje tehnikeState of the art

Prostore lahko prezračujemo na več načinov: - s kratkotrajnim in občasnim odpiranjem oken, ki ima za posledico vdor hladnega zraka v prostor, prepih in veliko izgubo toplote iz prostora pozimi in velik vdor toplote v prostor poleti (naravno prezračevanje) z lokalnimi ali centralnimi prisilnimi prezračevalnimi napravami, kjer se zrak čisti, predgreje ali ohladi in se brez prepiha in večjih izgub toplote dovaja v prostor (prisilno prezračevanje)Spaces can be ventilated in several ways: - with short and occasional opening of windows, which results in the intrusion of cold air into the room, drafts and a great loss of heat from the winter space, and a large incursion of heat into the summer space (natural ventilation) with local or central forced ventilation devices where the air is cleaned, preheated or cooled, and is fed into the room without forced drafts and major heat losses (forced ventilation)

Sodobne naprave za lokalno ali centralno mehansko prezračevanje prostorov imajo lahko vgrajeno napravo za rekuperacijo toplote odpadnega zraka, saj le tako zagotavljajo prezračevanje prostorov na energijsko učinkovit način.Modern devices for local or central mechanical ventilation of rooms can have a built-in device for heat recovery of waste air, as they only provide ventilation of the rooms in an energy efficient way.

Lokalno prezračevalni sistemi zagotavljajo večjo prilagodljivost, ker se lahko kakovost zraka uravnava v vsakem prostoru posebej. Potrebe po svežem zraku časovno in lokacijsko v stanovanju ali poslovnih prostorih ni možno natančno določiti. Tako so na primer zjutraj bolj obremenjeni sanitarni prostori, opoldne kuhinje, zvečer skupni bivalni in spalni prostori. Zaradi tega je lokalno prezračevanje tehnično veliko bolj prilagodljivo in zato povsod primerno in stroškovno učinkovito.Local ventilation systems provide greater flexibility because air quality can be controlled in each room separately. The need for fresh air time and location in the dwelling or business premises can not be accurately determined. For example, in the morning, the sanitary facilities, at noon, in the evening, the common living and sleeping areas are more loaded. For this reason, local ventilation is technically much more flexible and therefore everywhere appropriate and cost-effective.

Na tržišču ni znane naprave, ki bi uporabljala protitočen prenosnik toplote in bi istočasno zagotavljala podolgovato obliko. Na tržišču je veliko lokalnih prezračevalnih sistemov s prenosom toplote vendar so večinoma ploščate oblike ali imajo križni prenosnik toplote.There is no known device on the market that would use a counterweight heat exchanger and at the same time provide an oblong shape. There are many local heat transfer systems on the market, but they are mostly flat or have a cruciform heat exchanger.

Predmet izuma rešuje problem konstrukcije prezračevalne naprave podolgovate oblike s protitočnim prenosnikom toplote, ki sočasno omogoča: enostavno sestavo enostavno montažo na steno uporabo ene same odprtine v steni za dovod in odvod zraka poljubno lego na steni (od 0edo 360° okoli odprtine za dovod in odvod zraka) S tem so dane nove možnosti postavitve takšne naprave v bivanjskih prostorih.The subject of the invention solves the problem of the construction of a longitudinal shaped ventilation device with a counterweight heat exchanger which simultaneously enables simple assembly of simple wall mounting using a single opening in the inlet and outlet wall for any position on the wall (0 ° 360 ° around the inlet and outlet port air). This gives new possibilities for installing such an appliance in residential areas.

Opis nove rešitveDescription of the new solution

Predmet izuma je lokalna prezračevalna naprava, ki je podolgovate oblike, in vključuje protitočen prenosnik toplote in dvodelno predizdelano ohišje, ki je konstruirano tako, da je omogočena hitra in enostavna postavitev posameznih komponent prezračevalne naprave v vnaprej določeni konfiguraciji v ohišje, ki se nato opcijsko preko montažne plošče pritrdi na steno, pri čemer je za delovanje naprave potrebno izvesti samo eno odprtino v steno. Na ta način je omogočena hitra in enostavna montaža prezračevalne naprave na steno in njeno enostavno servisiranje. Podolgovata oblika pomeni, da so stranice naprave v eni smeri koordinatnega sistema izrazito daljše od stranic v drugih dveh smereh, kot je na primer oblika podolgovatega kvadra. Zračna tokova tako potekata vzdolž daljših stranic naprave za prezračevanje, kar zmanjšuje tlačne izgube toka zračnih tokov skozi napravo za prezračevanje.The subject of the invention is a local ventilation device which is elongated in shape and includes an countercurrent heat exchanger and a two-part pre-fabricated housing which is designed so that the individual components of the ventilation device in a predetermined configuration can be installed quickly and easily into the housing, the mounting plates are fixed to the wall, where only one wall opening is necessary for the operation of the device. In this way, quick and easy installation of the ventilation device on the wall and its easy servicing is enabled. The elongated shape means that the sides of the device in one direction of the coordinate system are markedly longer than the sides in the other two directions, such as the shape of the oblong square. The air flows are thus carried along the long sides of the ventilation device, which reduces the pressure losses of the flow of air streams through the ventilation device.

Zato, da je omogočeno optimalno delovanje podolgovate prezračevalne naprave, je potrebna optimizacija postavitve posameznih komponent prezračevalne naprave znotraj ohišja in sicer so posamezne komponente postavljene v ohišju linijsko, to je v določenem vrstnem redu oziroma zaporedju vzdolž daljših stranic ohišja. Prezračevalna naprava po izumu torej vključuje dvodelno predizdelano ohišje podolgovate oblike, ki ima na eni strani eno poleg druge izvedeno odprtino za dovod zunanjega zraka v napravo in odprtino za odvod notranjega zraka iz naprave v okolico, na drugi strani pa odprtini za dovod zunanjega zraka iz naprave v prostor in odprtino za dovod notranjega zraka iz prostora v napravo, predizdelano ohišje pa vključuje protitočni prenosnik toplote, ventilator za zunanji zrak, to je za sesanje zunanjega zraka iz okolice in sesanje le-tega skozi prenosnik toplote in nato po kanalu za zunanji zrak v prostor, ventilator za notranji zrak, to je za sesanje notranjega zraka iz prostora v kanal za notranji zrak in potiskanje le-tega skozi prenosnik toplote v okolico, glušnik zvoka s sočasno vlogo razdelilnika zraka na obe strani ohišja in predelno steno, ki poteka od protitočnega prenosnika toplote med obema ventilatorjema ob glušniku zvoka s sočasno vlogo razdelilnika zraka do stene ohišja in definira kanal za zunanji zrak in kanal za notranji zrak in preprečuje, da bi se zunanji in notranji zrak mešala.In order to optimize the operation of the elongated ventilation device, it is necessary to optimize the layout of individual components of the ventilation device inside the housing, so that the individual components are placed in the casing linearly, that is, in a certain order or sequence along the longer sides of the housing. The ventilation device according to the invention therefore includes a two-part pre-molded housing of an elongate shape, which has, on one side, one side of the second outlet for supplying outer air to the device and an opening for discharging the inner air from the device to the surroundings, and on the other side, an outlet for supplying outer air from the device into the room and opening for supplying the interior air from the room to the device, and the preformed housing includes a countercurrent heat exchanger, an external air fan, that is to extract ambient air from outside and to suck it through the heat exchanger and then through the outside air channel in space, the indoor air fan, that is, for sucking the inner air from the room to the inner air channel and pushing it through the heat exchanger to the surroundings, the silencer with the simultaneous role of the air distributor on both sides of the housing and the partition wall running from the counter flow a heat exchanger between the two fans with a silencer with a simultaneous role of the air distributor to the wall of the housing and defines a channel for outdoor air and a channel for indoor air and prevents the external and internal air from mixing.

Postavitev ventilatorjev za prenosnik toplote, to je na tako imenovani topli strani, je prednostna, saj sta v tem primeru ventilatorja pozicionirana centralno, to je pretežno v osrednjem delu prezračevalne naprave, s čimer se zmanjša hrupnost naprave. V eni od izvedb prezračevalne naprave sta lahko ventilatorja nameščena pred prenosnikom toplote na hladni strani, saj je s tem zagotovljeno, da se v primeru netesnosti zrak iz prostora ne more mešati z zunanjim zrakom. Slaba stran te namestitve pa je, da deluje ventilator za zunanji zrak v različnih temperaturnih pogojih.The installation of heat exchanger fans, that is, on a so-called hot side, is preferable, since in this case the fan is positioned centrally, which is predominantly in the central part of the ventilation device, thereby reducing the noise level of the device. In one embodiment of the ventilation device, the fans can be installed in front of the heat exchanger on a cold side, as this ensures that, in case of leakage, the air from the room can not be mixed with the outside air. The disadvantage of this installation, however, is that the external air fan operates in different temperature conditions.

Predizdelano ohišje je izvedeno iz dveh simetričnih delov, pri čemer ima vsak del ohišja na svoji notranji strani izvedene predelne stene in utore na vnaprej določenih mestih, tako da se znotraj ohišja definirajo prostori, ki so dimenzijsko prirejeni posameznim komponentam prezračevalne naprave in v katere se vstavijo posamezne komponente prezračevalne naprave v vnaprej določeni postavitvi. Vsak del ohišja ima tako na svoji notranji strani izvedene predelne stene za pozicioniranje ventilatorjev, predelno steno za ločevanje zunanjega in notranjega zraka, to je za definiranje kanalov za zunanji in notranji zrak v predelu pritrditve ohišja na stensko cev, utore za pozicioniranje in tesnenje prenosnika toplote in utore za vstavitev delilne stene. Robovi posameznega dela ohišja so izvedeni tako, da ob sestavitvi obeh delov ohišja robovi oblikosklepno nalegajo en na drugega. Izvedba in pozicija robov, predelnih sten in utorov zagotavljajo, da ko se vse komponente prezračevalne naprave vstavijo v predvidene prostore in se oba dela ohišja povežeta (sestavita), zadostno fiksiranje posameznih komponent prezračevalne naprave v definirane prostore, da se le-ti ne morejo neželeno premikati in zadostno tesnenje, da se zunanji in notranji zrak pri prehodu skozi prezračevalno napravo ne mešata.The pre-fabricated housing is made of two symmetrical parts, each part of the housing having partitions and grooves on predefined positions on its inside, so that within the casing there are defined spaces that are dimensionally adapted to the individual components of the ventilation device and into which they are inserted individual components of the ventilation device in a predetermined setting. Each part of the housing has both internal partitions for positioning the fans, a partition wall for the separation of the external and internal air, that is, for defining channels for the external and internal air in the area of fixing the housing to the wall pipe, the positioning and sealing grooves of the heat exchanger and grooves for inserting a dividing wall. The edges of each part of the housing are arranged in such a way that when the two parts of the housing are assembled, the edges are in contact with one another. The design and position of the edges, partitions and grooves ensure that when all components of the ventilation device are inserted into the intended spaces and the two parts of the housing are connected (assembled), sufficient fixation of the individual components of the ventilation device into the defined spaces so that they can not be undesirable move and sufficiently seal so that external and internal air does not mix when passing through the ventilation device.

Ohišje je povezano s stensko cevjo, ki je vstavljena v odprtino izvedeno v zidu. Ker je za delovanje prezračevalne naprave potrebna le ena odprtina v steni, je potrebno tudi v stenski cevi zagotoviti, da sta zunanji in notranji zrak pri prehodu skozi stensko cev ločena. To je lahko izvedeno tako, da skozi stensko cev potekata dva kanala, eden za zunanji zrak in drugi za notranji zrak, pri čemer se en kanal pritrdi na odprtino za dovod zunanjega zraka v napravo, drug kanal pa na odprtino za odvod notranjega zraka iz naprave v okolico. Lahko pa ima stenska cev v notranjosti po svoji celotni dožini, prednostno po sredini, izvedeno pregrado, s čimer se tvorita dva kanala, in sicer kanal za zunanji zrak in kanal za notranji zrak. Pregrada nalega na utor izveden na predelni steni izvedeni v ohišju. V prednostni izvedbi ima vsak od v kanalov prečni prerez v obliki polkroga. Ustrezen naklon stenske cevi za odtekanje kondezata iz prezračevalne naprave je lahko izveden z montažo stenske cevi, in sicer je stenska cev montirana pod naklonom, tako da kondenzirana tekočina teče v smeri od prezračevalne naprave ven proti okolici. V prednostni izvedbi je stenska cev montirana horizontalno in je ustrezen naklon zagotovljen s spreminjanjem debeline stene stenske cevi in sicer tako, da je notranja stena izvedena z naklonom, kar je konstrukcijsko rešeno s spreminjanjem debeline stene stenske cevi. Za zagotovitev nemotenega odtekanja kondenzirana tekočina v smeri od prezračevalne naprave ven proti okolici je naklon vsaj 1%.The housing is connected to a wall tube that is inserted into the opening in the wall. Since only one wall opening is required for the operation of the ventilation system, it is also necessary to ensure that the outer and inner air in the wall through the wall is separated in the wall tube. This can be done by ducting two channels through the wall pipe, one for the outside air and the other for the interior air, one channel being attached to the outlet for supplying the outer air to the device, and the other channel to the outlet for discharging the inner air from the device to the surroundings. Alternatively, there may be a wall tube inside the entire height, preferably in the middle, of a barrier, thereby forming two channels, namely, the outer air channel and the inner air channel. The barrier rests on a groove made on a partition wall in a housing. In a preferred embodiment, each of the v channels has a cross-section in the shape of a semicircle. An appropriate inclination of the wall conduit drainage tube from the ventilation device can be made by mounting the wall tube, namely, the wall tube is mounted under a slope so that the condensed liquid runs in the direction from the ventilation device to the outside. In the preferred embodiment, the wall tube is mounted horizontally and an appropriate slope is provided by varying the thickness of the wall of the wall tube in such a way that the inner wall is provided with a slope, which is structurally solved by varying the thickness of the wall of the wall tube. In order to ensure a smooth flow of condensed liquid in the direction from the ventilation device to the outside, the inclination is at least 1%.

Opcijsko je povezava ohišja s stensko cevjo lahko izvedena preko nastavka. Na ohišje se nad izvedeno odprtino za dovod zunanjega zraka v napravo in odprtino za odvod notranjega zraka iz naprave v okolico pritrdi nastavek, ki ima centralno izvedeno odprtino predostno okrogle oblike, ki z notranjo površino nalega na predelno steno izvedeno v ohišju in na robove omenjenih odprtin, s čimer je omogočena dodatna zatesnitev in preprečitev, da bi se zunanji in notranji zrak v predelu pritrditve ohišja na stensko cev mešala. Na zunanji površini ima nastavek okoli odprtine izveden utor, v katerega se vstavi stenska cev.Optionally, the connection of the housing with the wall tube can be carried out via the attachment. A nozzle having a centrally-formed opening is predominantly circular in shape, which is mounted on the partition wall in the housing and on the edges of said openings over the derived opening for supplying the external air to the device and the opening for the discharge of the inner air from the device to the surroundings , thereby providing additional sealing and preventing the external and internal air from mixing the casing into the wall mounting area. On the outer surface, the nose around the opening is a groove into which a wall tube is inserted.

Ohišje in nastavek sta izvedena iz materialov, ki jih je možno primerno oblikovati v kalupih, prednostno sta izvedena iz izolativnih materialov in sicer iz ekspandiranega polistirena.The housing and attachment are made of materials that can be shaped in molds, preferably made of insulating materials, from expanded polystyrene.

Ventilatorja sta električna in vključujeta ohišje ventilatorja in rotor z lopaticami, pri čemer je odprtina za sesanje zraka izvedena na bočni stranici ohišja ventilatorja, odprtina za izpihovanje zraka pa na prednji stranici ohišja. Ventilatorja sta v predizdelano ohišje postavljena tako, da sta odprtini za sesanje zraka obrnjeni pretežno ena proti drugi in sta med sabo ločeni s predelno steno, odprtini za izpihovanje zraka pa sta usmerjeni vsaka v svoj kanal. Ohišji ventilatorjev in s tem odprtini za sesanje zraka in odprtini za izpihovanje zraka sta postavljeni v predizdelano ohišje ali vzporedno z daljšimi stranicami predizdelanega ohišja ali sta zarotirani eno na drugega pod kotom glede na daljše stranice predizdelanega ohišja za maksimalno 30 kotnih stopinj in tako, da osi odprtin za sesanje zraka ležita ali na isti navidezni premici, ki povezuje obe osi ali se njuni osi nahajata na navideznih vzporednih premicah, ki sta zamaknjeni v vzdožni smeri prezračevalne naprave, to je v vzdolžni smeri daljših stranic ohišja, za zamik, ki je največ enak premeru odprtine za sesanje zraka. V prednostni izvedbi sta ohišji ventilatorja in s tem odprtini za sesanje zraka in odprtini za izpihovanje zraka postavljeni v predizdelano ohišje vzporedno z daljšimi stranicami predizdelanega ohišja in tako, da osi odprtin za sesanje zraka ležita na isti navidezni premici, ki povezuje obe osi.The fans are electrically incorporating a fan housing and a rotor with blades, the air suction port being carried out on the side of the fan housing, and the air outlet on the front of the housing. The fans are arranged in a prefabricated housing so that the air suction ports are predominantly facing one another and are separated by a partition wall each other, and the air outlet ports are directed each to their channel. The fan housings and with this air suction port and air outlet are placed in a pre-fabricated housing or in parallel with longer sides of the pre-fabricated housing or rotated at one another at an angle with respect to the long sides of the pre-fabricated housing for a maximum of 30 angular degrees and so that the axes the air suction openings lie either on the same apparent line linking both axes or their axes are located on apparent parallel lines displaced in the longitudinal direction of the ventilation device, i.e. in the longitudinal direction of the longer sides of the housing, for a lag which is at most the same the diameter of the air suction port. In a preferred embodiment, the fan housing and thereby the air suction port and the air outlet are positioned in the preformed housing in parallel with the longer sides of the preformed housing and so that the axes of the air suction ports lie on the same virtual bar that connects both axes.

Funkcija predelne stene je, da preprečuje, da bi se zunanji in notranji zrak pri prehodu skozi prezračevalno napravo mešala, torej definiranje kanalov za zunanji in notranji zrak, in zagotavljanje optimalnega vtoka sesanega zraka v ventilatorja. Oblika predelne stene je v predelu med ventilatorjema izvedena pod kotom tako, da zagotavlja ustrezen vtok sesanega zraka v ventilatorja. Med ohišjem in prenosnikom toplote je izvedeno dvojno tesnenje s tesnilkami, v obliki votle cevke iz materiala, ki je odporen proti staranju, ki nalegajo v utor v ohišju. Posebej je izvedeno tesnenje s tesnilkami med vsakim ventilatorjem in predelno steno, s čimer se zagotavlja ustrezno tesnenje in se prepreči, da bi se zračna tokova na sesalni in tlačni strani ventilatorja mešala. Glušnik zvoka s sočasno vlogo razdelilnika zraka, ki je pozicioniran za ventilatorjem za zunanji zrak, ima dve funkciji, in sicer deluje kot glušnik zvoka, s čimer se zmanjša hrup prezračevalne naprave, in za razdelitev zraka na levo in desno stran prezračevalne naprave, kjer odhaja skozi iztočne vrtljive šobe, ki so izvedene na zaščitnem ohišju, v prostor. Iztočne vrtljive šobe omogočajo neomejeno prilagajanje dovoda zraka v prostor.The function of the partition wall is to prevent the external and internal air from mixing through the ventilation device, that is, defining the channels for external and internal air, and ensuring the optimal flow of sucked air into the fan. The shape of the partition wall is carried out at an angle between the fans between the fans in such a way that it ensures an adequate flow of sucked air into the fan. A double sealing with seals is provided between the housing and the heat exchanger, in the form of a hollow tubing made from an aging resistant material that fits into the groove in the housing. Especially sealing with gaskets between each fan and the partition wall is made, ensuring proper sealing and preventing the airflow from mixing at the suction and pressure side of the fan. The silencer with the simultaneous function of the air distribution distributor, which is positioned as an external air fan, has two functions: it acts as a silencer, reducing the noise of the ventilation device, and for distributing air to the left and right sides of the ventilation device where it goes through the outlet rotating nozzles, which are carried out on the protective housing, into the room. The outlet rotating nozzles allow unlimited adjustment of the air supply to the room.

Opcijsko prezračevalna naprava vključuje filter za zunanji zrak in filter za notranji zrak, pri čemer je filter za zunanji zrak nameščen v ohišje za odprtino za vstop zunanjega zraka v prezračevalno napravo in pred prenosnikom toplote, filter za notranji zrak pa je nameščen nad odprtino za vstop notranjega zraka v prezračevalno napravo. Za enostavno menjavanje filtra za zunanji zrak je v ohišju izvedena reža.The optional ventilation device includes an external air filter and an internal air filter, wherein the outer air filter is located in the housing for the opening for entering the outer air into the ventilation device and before the heat exchanger, and the inner air filter is positioned above the opening for the entry of the inner air into the ventilation device. To easily change the outside air filter, a slot is made in the housing.

Opcijsko prezračevalna naprava vključuje grelnik zunanjega zraka, ki je v ohišje prednostno nameščen pred filtrom za zunanji zrak.An optional ventilation device includes an external air heater which is preferably positioned in front of the outside air filter in the housing.
